Pretty sure NV 3D Vision has been deprecated and is now unsupported. The driver packages no longer contain the driver(s) for "3D Vision".
Given that, are you sure that you want/need them? Rather than a newer (but still likely to be abandoned tech soon) VR Helmet?
The new display would replace the DLP monitor.
Indeed. The NVidia 3D Vision glasses were active shutter type. In principle, you just need high refresh rate display.i thought you needed Active shutter 3D for 3d N Vision.
